Specification of Letters Patent.

Application filed March 27, 1917. Serial No. 157,735.

To all whom it may concern Be it known that I, J OHN A. BANsoHBAoH, a citizen of the United-States, residing at Shelbyville, in the county of Shelby and State- 0f Indiana, have invented a new and useful Automati Tape-SealingMachine, of

which the following is a specification.

The object of my invention is to provide a novel automatic tape sealing machine to seal packages, etc., with gummed tape; and to provide such a machine adapted to carry more than one roll of tape.

I attain the objects of my invention by the mechanism illustrated in the accompanying drawings, in which- V Figure 1 is a side elevation of my invention; Fig. 2 is a top plan of same; Fig. 3 is a Vertical section; Fig. 4 is a front view; and Fig. 5 is a detail of a modified form of the invention.

Similar numerals designate similar parts throughout the several views.

Referring to the accompanying drawings, I provide a suitable tape receptacle 1, having a cover 2, a rod 3 mounted on member 1 and carrying one or more (preferably two) tape rolls 4. These tape rolls may be of different width. I provide a suitable trough 5 containing water within which is revolubly mounted a moistening roll 6, carried by shaft 7. Secured'to the end of shaft 7 is a pinion 8, meshing with a larger pinion 9, which in turn meshes with a relatively large gear wheel 10 mounted on shaft 11. Shaft 11 also carries, at its other end, a pinion 12, which meshes with gear 13, upon which tension is exerted by spring 14. A suitable tape guide roll 15 presses the strip of tape 4 against moistener roll 6, under the tension of a suitable small spring 16, as shown in Fig. 3. Aflixed to shaft 11 is a suitable cam wheel 17, with which a finger lever 18 is adapted to engage, lever 18 normally being held in engagement with cam wheel 17 by means of a suitable spring 19. Tape guide roll 15 is mounted between suitable arms 20, which. are slidably mounted on rod or shaft 21, as "shown in Fig. 2.

ltteferring to Fig. 5, a modified form of the invention as to certain details is illustrated. I provide a modified form of finger lever 22, corresponding in its function with lever 18; a spring 23 corresponding with spring 19 of the other form, and exerting tension 9n the finger lever; and a pawl 24:

suitably attached to lever 22 and adapted to actuate gear wheel 10. I may provide a plurality o pinions 9 intermediate of members 8 and 10, as illustrated in Fig. 5. A suitable spring 25 engages pawl 24.

In operation the finger is pressed on the button end of finger lever 18, thereby lifting 1ts end out of engagement with cam 17 The shaft 11 in which cam 17 is mounted is thereby perrnltted to revolve, actuated by sprin ll caus ng a length of tape to be unrolled and passed over the moistening roll. The tape is then torn off against the sharp outer edge of the cover 2 over the moistening roll. Each time the same length of tape comes forth when the finger lever is operated. Different sizes of cam wheels may, however, be supplled to vary the length of tape accordlng to the requirements of the user. The coil spring may be wound up at infrequent intervals as required. This usually is about as often as an eight-day clock. The tape is molstened automatically as it unrolls. Just the required amount of moisture is obtainable by regulatinglthe pressure exerted by sprlng 16 on arms 20 which carry the tape guide or pressure roll 15. Roll 15 may be shifted to either side of the machine so as to operate either of the two rolls of tape with which the machine is ordinarily supplied. When operating on one side, the tape on the other side does not unroll as no pressure 1s exerted on it. A change can very quickly be made on a narrow tape to a wide tape, or vlce versa, according to the size of the package to which it is to be applied.

1518 within the contemplation of my in- VGIItIOII to employ the modified form illustrated 1n Fig. 5. lln this form of the invention a suitable pawl 24:, pivoted to finger lever 22, engages gear wheel 10 to actuate a serles of pmions operatively connected with moistener roll 6. No spring 14 is employed 111 this form of the invention:

I may provide suitable thumb nuts 26 on the end of shaft 3 to facilitate the adjustment of the tape rolls.

What I'claim is:

1. In an automatic tape sealing machine, means to hold a plurality of rolls of tape, a single laterally shiftable tape guide roll adapted to engage either of the tapes, a pressure roll, a moistener roll, a spring tensioned finger lever, geared mechanism operable by the finger lever, and arranged to rotate the Patented July 23, TFTF.

moistener roll to cause a strip of moistened tape to be discharged for use, substantially as shown.

2. A structure as speclfied in claim 1 in combination with a spring and gear mechanism actuated thereby to exert constant pressure to efiect the automatic unwinding of the tape roll when the finger lever is depressed.

3. In a device of the class described, means for holding one or more rolls of tapecomprising a casing having a hinged cover, a roll holding shaft having thumb nuts on its ends, a spring tension pressure roll mounted over a moistener, a trough adapted to hold Water, a moistener roll mounted in the trough over which the tape is unwound, means pgeratively connectin the moistencr roll wit a finger lever, an a spring tensioned finger lever adapted to intermittently unroll the tape.
